jean-pierre charras aa4de22ef4 EDA_3D_CANVAS: fix crash when used in dialogs and clicking in the 3D shape
It was due to the fact a message (using ExpressMail) was sent to the board
and schematic editor, but it is possible only if the manager of this canvas
is a EDA_3D_VIEWER_FRAME, because only this kind of frame has ExpressMail stuff
